That is a business intention and plan, not a promise. Apple is also planning to sell foldable iphones in a few years, but hasnt done it yet. Not a promise either.
CIG has actually pre sold and cashed in money in exchange for all Kickstarter and Strechgoal promises, among many other things, undelivered 9+ years on. Those are actual committments and liabilities owed to the backers.
Yes, and this is my biggest problem with Star Citizen. As a dude who used to work in game dev, priorities and mechanics are dropped or shifted around all the time. Tent-pole features might not be feasible or fun and need to be dropped or massively changed. It sucks, but hey, that's the nature of game development. But if you pre-sell those features, you're on the hook for making them a reality or refunding the pre-orders when you can't deliver. It opens you up to huge liabilities.
Any sane game dev at the ten year mark of an unreleased product would've dropped a ton, a TON of Star Citizen's promised features until they got the basics of the game feeling right. They would not have pre-sold capital ships for thousands of dollars until they knew the technology was in place to create that gameplay.
What Star Citizen promised, they simply can't deliver with their current engine and staff. They'd have to go back to the beginning and
still might not be able to achieve what they've pre-sold. They're on the hook for tens -- if not hundreds -- of millions of dollars of pre-ordered DLC for a pre-ordered game stuck in pre-alpha development hell.
You do have more oversight now -- between whatever 3rd party the Calders brought in (still don't have a company name for em) to review monthly and quarterly progress and Turbulent taking over more and more responsibilities (including Server Meshing), I do think you'll get some kind of "release" in the next three to six years. But it will be extremely, extremely tamped down from whatever zany promises Chris & Co made over the last ten years.
Watching streamers melt down over the last "No Capital Ship PvP" leak will give you a glimpse of what's to come here in the next 36 months.
